2 Claims.

Thepresent invention relates to new and useful improvements in means forapplying cement to sheet roofing material and has as its principalobject the provision of a portable machine which can be easily rolledalong to apply cement or other adhesive toroll roofing material alongthe edge portion thereof that is tobe cemented in place.

The principal object of the present invention is to provide a smallmachine of the character stated which can be easily rolled along aninclined roof without likelihood of spilling any of its contents.

Another important object of the invention is to provide a machine of thecharacter stated which can be replenished with cement from time to timein an easy and convenient manner.

Another important object of the invention is to provide a roll roofingmaterial cement applying machine which will apply cement in an even anduniform manner.

These and other important objects and advantages of the invention willbecome apparent to the reader of the following description.

In the drawings Figure 1 representsa side elevational view of themachine with a step of roofing material shown engaged.

Figure 2 is a back end elevational view of the machine.

Figure 3 is a top plan View.

Figure 4 is an enlarged longitudinal sectional View.

Figure 5 is a vertical sectional view on the line 5-5 of Figure l.

Figure 6 is a transverse vertical sectional View taken substantially onthe line 66 of Figure 4.

Figure 7 is an enlarged fragmentary horizontal sectional view takensubstantially on the line 1-1 of Figure 1.

Referring to the drawings wherein like numerals designate like parts, itcan be seen in Figure 1, that numeral 5 denotes a roof base upon which.hasbeen laid a strip of roofing material 6 and over this strip a strip 1is to be overlapped after application of cement to the overlapping edgeportion. In Figure 1, numeral 8 generally refers to the improved machineshown engaged with the overlapping edge portion of the strip 7.

The machine includes a rectangular-shaped tank 9 having positioned andsuitably secured in upright position in one corner portion thereof atube l0 having a can punch II at its upper end projecting upwardly abovethe top of the tank, so that a can-of c'ement can. be inverted, pusheddownwardly on the opener II, with the result that the contents will rundirectly into the tank 9:

Atthe inside of the tank andsecured to the endwalls thereof are U-shapedbearings l2, l2 for receiving the end portions of. a horizontal shaftl3. On the shaft [3 adjacent the rear end of' the tank 9- is a roll l4having two rows of small projections 15, i5 circumferentiallyextendingabout its periphery for the purpose of adding traction and maintainingthe roll l4 revolving as it is moved along the edge portion of a stripof roofing material.

Adjacent the roll M and mounted upon each side wall of the tank 9 is aframe IS in which is mounted a smaller roll 11. These rolls are mountedso as to have their lowermost portions somewhat below the topmostportion of the roll I4.

J The frames l6 are of general inverted U- sha-pe, each having one legspaced from the tank 9 while its other leg is attached to the tank andthis latter leg has a pair of vertically spaced ears I 9, I9 betweenwhich is mounted a vertically disposed roll 20 preferably smaller thanthe roll H and serving as an abutting roll for the adjacent edge of theroofing strip being cemented.

A substantially inverted V-shaped handle 2| is provided for the device,the leg portions thereof being welded or otherwise secured to theoutside of the side walls of the tank 9.

Under the rolls H, the adjacent edge portions of the tank 9 are providedwith short upstanding teats 22 which serve to prevent wiping of theentire coated surface of the roofing strip against the tank.

The back end of the tank 9 has a bracket 23 in which is mounted a roller24, while at the forward end of the tank 9 is an outstanding ear 25having an opening therethrough for receiving the shank 2B of a casterwheel unit 21. The ear 25 is formed with an opening to slidably receivethe shank 26 of the caster wheel'unit 21. A horizontal threaded bore isformed in the ear to receive a set screw 28 which can be driven againstthe shank 26 to support the tank on a true horizontal plane regardlessof the pitch of the roof.

In the operation of this device, the edge portion of the buildingmaterial strip 1 is interposed between the rolls l4, I1, I! after aquantity of cement has been placed in the tank 8.

As the machine is pushed along, the projections I5, IS on the roll itwill ride the roofing strip and the roll M will carry from the tank 9cement and apply the same to the corresponding edge portion of theroofing strip.

While the foregoing specification sets forth the invention in specificterms, it is to be understood that numerous changes in the shape, sizeand materials may be resorted to without departing from the spirit andscope of the invention as claimed hereinafter.

Having described the invention, what is claimed as new is:

l. A machine for applying roofing cement to i one edge of a, strip ofroofing material comprising a wheel-supported cement containing tankadapted to travel over a roof with one side underlying said edge of thestrip, a cement applicator roller in said tank projecting peripherallyabove the same for engagement with the under side of said edge of thestrip and mounted in said tank for rotation about an axis at a rightangle to the line of travel of the tank whereby said roller is caused toroll along said edge under travel of the tank and by frictionalengagement with said edge and to apply cement to said edge, a pair ofidler rollers mounted on said tank upon opposite sides of the applicatorroller, re spectively, parallel therewith for rolling along and oversaid edge of the strip to hold the edge down on the applicator roller,and means on said tank for engagement with the edge of the strip toguide the tank along said edge in a course parallel therewith.

2. A machine for applying roofing cement to one edge of a strip ofroofing material comprising a wheel-supported cement containing tankadapted to travel over a roof with one side underlying said edge of thestrip, a cement applicator roller in said tank projecting peripherallyabove the same for engagement with the under side of said edge of thestrip and mounted in said tank for rotation about an axis at a ightangle to the line of travel of the tank whereby said roller is caused toroll along said edge under travel of the tank and by frictionalengagement with said edge and to apply cement to said edge, a pair ofidler rollers mounted on said tank upon opposite sides of the applicatorroller, respectively, parallel therewith for rolling along and over saidedge of the strip to hold the edge down on the applicator roller, andmeans on said tank for engagement with the edge of the strip to guidethe tank along said edge in a course parallel therewith, said meanscomprising a pair of rollers mounted on said tank upon opposite sides ofsaid applicator roller, respectively, and rotatable about axes at rightangles to the axis of said applicator roller.
